RESERVE-SUPPLY TANK.

To all olio/n, 'it may concern y 3e it linovfn that l. llnnnlooi; E. GUB'IN, a citizen of Ythe United `States of America, and resident of Racine, Racine County, State of lill'ieconsin, have invented certain ueefil lisnprovenieiits` in and Relat -ve-luppl y Tanks, of which the a -epecilicatioa This, invention relates to means for assurfuel reserve in the liquid .fuel supply ine of motor velricles; and the objects :md nature of the invention 'will be readily understood by thoee Skilled in the art in the li; it of the following explanation of the alcompenyini;H drawinge` ill ilustrating, what l noir believe to be the preferred mechaf'cal expreeeion or embodiment of my invention from among other forme, con-- strut-tions and arrangements within the spirit and scope thereof. .y t

VBy reason of unpleasant experiences due to exhaustion of their fuel supply at locan tions far from gasoline supply stations, drivers of motor care appreciate the desirability and advantages of motor car fuel eupply lsysteme that provide for Small reserve supplies of fuel that can be drawn on vwhen the nri'nereeo of the motor car ie halted by erhiiustion of the main fuel Supplya tu object of my invention is to provide a simple and ellicient reserve fuel regulator bv means of which a small, reserve supply of fiiel can be established in a motor car -fuel tank, in readiness;` to be drawn on in ease of 'need by the manual manipulation of a device normally cutting' off flow of fuel from Said reserve to the cs rrlnireter.

toni portion of the main gasoline or other main liquid fuel Supply tank l of a motor vehicle Such as a motor car, motor boat or the like. This tank has a vertical bottom openingor outlet formed by vertical Socket or bore extending through a bushing or the like 2 fixed to the tank and fittinr in a hole in the tank bottom, in the uSual or any Suitable manner. I

Entrance to the tank for drawing oli' the fuel, established through this outlet, by means through which the fuel flows to the pipe or tube 3 leading' to the carbureter. Such means embody a 'tubular casing or coupling` 4 at its upper end forming a nipple or plug 5 fitted tightly in and extendingr through the bottom outlet of the tank and Secured therein to forni a liquid tight joint 'with the linishing` 2 by screw threads or other securingmeans. This tubular canine; depends from the tank bottom, and at its lower end is preferably eXteriorly formed, at 6, to receive a Wrench or other suitable tool by 'which the. casing' can be rotated for securing; in and removing from the tank outlet opening.

The casing` is also preferably formed with a longitigidinal Screw threaded socket 7 open'- ingj through its lower extremity, for 'the atn tachrnent of any suitable depending trap 8, to which the carbureter feed pipe 3 is coupled in any suitable manner. The arrangement Such that the liquid fuel flows down from the tank through casing 4 into the trap 8. The fuel flows laterally from the trap, at a point intermediate the depth thereof, into the carbureter feed pipe The trap is preferably provided with fuel cut off valve controlled by exterior accessible handle 9, by which the flow of fuel to the carbureter can be cut ofi'. as is understood by those skilled in the art.

rI he upper end of the trap forms a threaded nipple l0 to screw into the socket 7, while the lower end of the trap is formed with a drain opening normally closed by plug l'l. The trap has a side outlet formed to permit coupling of the pipe il thereto, so that the 'fuel for pipe 3 is drawn from the upper part of the trap, permitting precipitation of dirt and sediment in vthe trap. The ltrap is formed with a vertical liquid duc" l2 extending through the nipple l0 to receive the fuel from casing and discharge the same into the trap chamber, and this duct is con` trolled by the plug valve operated by handle 9.

The casing 4 provides a main fuel supply duct 13 leading from the interior 0f the tank 1, to the socket 7, and also a reserve fuel or auxiliary supply duct 14 leading from the interior of said tank 'to the socket '7. The lower or outlet ends of ducts 13, 14, lopen through the top wall of socket 7, so that the lower ends of both said ducts are in free and unobstructed communication with the upper 0r inlet end of duct 12 when the trap is secured to the casing 4, as shown by Fig. 1.

The upper or inlet end of main fuel supply duct 13 is arranged in tank 1, a distance above the bottom of said tank, to establish a reserve fuel supply, while the upper or inlet end of reserve fuel duct 14 is flush or approximately level with the lowest portion of the fuel tank bottom so that the tank can be approximately drained through duct 14.

The main supply duct 13 is open and unobstructed throughout its length for the free flow of fuel to the trap, whereas the reserve fuel duct 14is normally closed against fuel passage. Theelevated inlet of the main supply duct 13 to provide the reserve fuel' supply in the tank, is, in the example illus-- trated, established by an upstanding or vertical- 'tubular extension 15 of the casing 4. The tube 15. is open at its upper end for inflow of fuel and the Otherwise iinperforate lengtlfi of the tube above the upper end of the casing 4 determines 'the level of the .reserve fuel supply. This tube 15 can be made in one piece with casing 4, or can be formed by securing a short lengthof straight tube to said casing. Usually, the length of tube 15- is such as to provide a reserve fuel supply of approximately one gal-lon more or less.

The ducts 13, 14, are usually separate and extend longitudinally through the casing 4. The duct 14 opens through the upper end of the casing 4 about flush with the tank floor, and' this duct is traversed and normally closed by rotary plug valve 16 extending transversely through the easing 4 and duct 14 andY provided with exterior operating handle 17. The plug of this valve 16 is formed with a transverse side recess or passage 18 located intermediate the length of the plug and adapted to be brought into alinement with the duct 14 to open the duct to flow of fuel past the valve (see Fig.

A supplemental cut off or valve 19 is also provided within the tank to cover and nir cover the inlet end of duct 14 and prevent collection of sediment in the upper end of said duct as well as to clear sediment from the tank bottom at Athe duct inlet when said inlet is opened by movement of said Vabre. In this instance, l show a reciprocating cap or disk valve 19 secured to the upper end of straight stem 20 and carried thereby. This missin is of such size and form as to lit down on the upper end 0f said casing and close and cover the inlet end of said duct when said valve is at its limit of downward movement, and to permit free flow of fluid from the bottom of the tank into duct 14 when said valve is at its limit of upward movement. rllhe spring Q2 constantly acts to hold the head 21 against the surface of the rotary valve 16 and constantly tends to hold valve 19 in closed position or to return the same to closed position, and the rotary valve is so formed where engaged by head 21, that when the rotary valve is inposition closing the duct 14, the reciprocatory valve 19 will autoinatically assume its position covering and closing the inlet end of duct 14, and when rotary valve 16 is rotated to open the duct 14 (Fig. 3) the valve 19 will be automatically lifted to uncover the inlet end of duct 14, and when the rotary valve is rotated to close the duct 14, the valve 19 will automatically descend to cover and close said inlet end of the duet. The surface ofthe rotary valve acts as a tain in raising the spring pressed val ve 1.9 and permitting descent thereof, 'through the medium of the valve stem 2t) and its head 2l. The surface of the passage or depression lc in the rotary valve and the relatively elevated duct closing portion thereof are utilized for this purpose in cooperating with head 21.

If the motor car driver permits his .sup` ply of fuel to become exhausted to the liquid level of the inlet end of projecting tube 15, the motor will stop. Un investigation, the driver will discover that his fuel is exhausted except for the supply held in reserve in the tank by the elevation of the main supply inlet 15. The driver will then swing the valve handle 17 down from the horizontal position (Fig. 1) to the vertical position (F 3) thereby-opening the duct 14, and elevating closure valve 19 to uncover the inlet in the tank bottom to duct 14.

The closure valve 19 not only prevents sediment from collecting in and closing the upper end of duct 14 above the rotary valve 1G. but also forcibly clears sediment in the 'tank above theI valve and opening. when the valve is forcibly elevated by the rotation of valve lo.

lt will also be noted that the means for establishing the reserve supply in the main fuel tank and for controlling said reserve supply, are all carried by the casing` 4, and hence that no change is required in tank and pipe line constructions, and that my improvement can be easily applied to motor vehicles as new constructed, as ivell as to those now in use.
